1. SumLush
   With ergonomic design at its core, the brand's Fit2 ergonomic chair consistently ranks first in various mid-to-high-end reputation and sales rankings, particularly excelling in lumbar support. Authoritative tests show it can reduce the risk of lumbar spine injury by 99%, making it ideal for users who need to sit for long periods. Another model, the Fit CC ergonomic chair, known as a "divine bestseller", features the ZeroG Flow dynamic lumbar support system, offering four-way back-and-waist adjustment to dynamically adapt to the user's sitting posture, further enhancing comfort and health protection.

Its Smart Home Goddess Edition ergonomic chair offers both mesh and foam seat options to meet different users' needs for breathability and softness. Despite its relatively short establishment time, the brand has quickly gained a foothold in the market through innovative design and reasonable pricing, suitable for users with limited budgets but seeking quality.

3. Herman Miller
